Engineered for demanding heavy-duty diesel service, this Mechanical Unit Injector (MUI) is manufactured to fit 3116 and 3126 diesel engines equipped with mechanical fuel injection systems. Identified by primary OE number 127-8218 and remanufactured reference 0R-8684, the injector features an 8 mm plunger size and delivers precise fuel metering, stable combustion, and consistent power output under continuous industrial workloads. Aftermarket catalogs additionally list part DS-127-8218 as a compatible reference for 3114, 3116, and 3126 applications.

The injector is widely applied across a broad range of off-highway machinery, including the IT62G integrated toolcarrier, Challenger 35 / 45 / 55 tractors, Wheel Loader 950G / 960F / 962G, Skidder 525B / 535B, and forestry machines TK370 / TK371 / TK380 / TK381, as well as 533, 543, 570, and 580 series units. Supplier cross-reference numbers 107-7735, 156-5023, and 20R-2052 should be verified against the engine serial number and original injector specification prior to shipment to ensure correct fitment.

Ideal for diesel repair shops, remanufacturing suppliers, heavy equipment fleets, and global parts distributors, this injector supports engine overhaul, injector replacement, and complete fuel system maintenance. Note that this product is intended for mechanical injection systems only and is not compatible with electronic common rail engines.
